Imports:

Description:
        CommonDialog is a convenience component that provides a dialog with the platform-style title area. You only have to define titleText. CommonDialog handles its layout automatically.
        Note: This component is experimental, so it may be changed or removed in future releases.

Properties:
        string titleText: the title of the dialog.
        string titleIcon: the name or path of the dialog title icon
        Array variant buttonTexts: the texts of all the buttons

Signals:
        buttonClicked(int index):
        Emitted when the user clicks on a button
        @arg int index: the index of the clicked button: buttonTexts[index] will hold the text of the clicked button.
